A peek review with our next generation World Lamp

We are making our next generation World Lamp shell. What shows in this photo is a prototype of 2.5mm coroplast, the real deal will be made with 4mm coroplast, which is much stronger than existing lamp shell.
We moved its opening to top of lamp, and use tab insert instead of snap lock to latch the cover pan.
Everything else remain the same, you still get a nice 30 watt LED core to shine through exactly the same dual lamp windows. The only thing that's going to change is color. Which color should we pick?
